Computational Aeroacoustics Analysis Strategy and Requirements

Computational Aeroacoustics (CAA) is a specialized discipline that leverages computational fluid dynamics to analyze and model acoustic phenomena.

This course begins with a foundational overview of CAA, highlighting the physical characteristics of fluids and solids that influence acoustic behavior. You will delve into key parameters critical to successful CAA simulations, such as the Convective and Acoustic Courant numbers. The course also addresses common implementation challenges, offering practical guidance on mesh design, time step selection, and other best practices to enhance simulation accuracy.

Finally, you will gain hands-on experience configuring CAA physics within Ansys Fluent® fluid simulation software. This includes setting up energy equations, defining fluid properties, selecting solver methods, and applying appropriate boundary conditions tailored for aeroacoustics analysis.

Learning Outcomes:

Following completion of this course, you will be able to:

• Understand the techniques to master the resolution of low-frequency waves.
• Understand the implementation of sponge layers in CAA.
• Achieve proficiency to model and analyze acoustic phenomena effectively.
